U.S. endurance swimmer Diana Nyad is making final preparations for her bid to become the first person to swim the Florida Straits without the aid of a shark cage.  Read more after the jump.

Nyad is spending the day eating, hydrating and meeting with members of her support team ahead of the 103-mile (166-kilometer) swim from Havana to the Florida Keys.

The 61-year-old swimmer will be accompanied by 45 people on five boats during the trip, which is expected to take about 60 hours.

Special equipment will surround her with an electric current that Nyad won’t notice, but will keep most sharks at bay. Divers will be at hand to discourage those that get curious.

She expects to depart Sunday evening.
